FLUSHING DEVICE.

Specification of Letters Patent.

Patented May 24, 1910.

Application filed January 4, 1910. Serial No. 536,415.

To all wlwm it may concern:

Be it known that we, HARRY M. SMITH and DANIEL Knivnvnn, citizens of the United States, residin at Denver, in the county of Denver and tate of Colorado, have invented certain newand useful Improvements in Flushin Devices, of which the following is a specifibation, reference being had to the accompanyin drawings.

This invention re ates to certain new and useful improvements in flushing devices for sinks, washbowls, rease traps and the like, and has for its (ibject to provide an improved device of this character which is of great convenience, simplicity, and effectiveness.

Another object is to provide a flushing device for the purpose specified which is adapted for use by persons without skill or experience in the use of flushing apparatus.

A further object of the invention is to.

provide a device which may be quickly attached to the faucet or spigot, and is easily and effectively operated without necessitatin undue manual labor,

- 'ith these and other objects in view, the

invention consists of the novel construction, combination and arrangement of parts hereinafter fully described and claimed and illustrated in the accompanying drawings, in which- Figure 1 is a section through one end of a sink showing the application of our improved fiusher, Fi 2 is an enlarged vertical section throug the suction head; and Fi 3 is an end elevation of the head.

eferrin to the drawin s 5 indicates a sink of or inary form usually found in the kitchens of private residences, and 6 is the 's igot or faucet which supplies the water t ereto from the main ipe. One end of a flexible hose 7 is provi ed with a coupling head 8 for attachment to the faucet said hosebeing preferably formed of rubber and provided in its other end with a screw threaded shank 9. This shank is formed with a peripheral flange 10 adjacent to its outer end, and the projecting end portion of the shank is provided with exterior screw threads. p

The con ling head 11 comprises a cylindrical tubu ar portion which is flanged at its outer end as shown at 12 and a laterally inclined circumscribin flange 13 extends fromthe edge of the ange 12. The other held within the flanged end of the It will strike the perforated end of the cylindrical body portion of the suction'head has an opening 14: formed centrally therein which is adapted to receive the threaded extension of the shank 9. A nut 10 has threaded engagement on the end of the shank and frict-lonally engages the inner surface of the closed end of the suction head whereby the head is securely retained in position thereon. A flexible member 15 is seated in the outer end of the suction head upon the flanges l2 and 13 thereof. This member extends beyond the edge of the flange 13 and is adapted to be firmly held in engagement with the surface of the sink by the suction created Within the head in the operation of the device. This flexible member is secured in the end of the head by means of the annular plate or 'ring 16 which is disposed upon the same on the flange 12. A plurality of threaded bolts 17 are disposed through openings in the flange and in the ring 16. huts 18 are threaded upon the outer ends of these bolts and are securely engaged upon the ring 16 whereby the flexible suction member 15, is securely head.

In the operation of the device the flexible hose 7 is attached to the spigot or faucet and the water turned into the same. The flexible suction member 15 is positioned over the perforated plate usually disposed in the upper end of the drain pipe. As above stated the suction which is induced will cause the outwardly extending circumscribin edge portion of the member 15 to closely adiere to the surface of the sink and retain the head in its proper position over the drain The water will be discharged throu into t e cylindrical portion of the head 11. late in the drainage pipe with conside'rab e force and effectively remove grease, dirt, or other foreign matter which has accumulated in the opening thereof. In this manner the drain pipes of sinks, washbowls, grease tra s, etc., may be very quickly and effective y relieved of the matter which has accumulated therein and which often results in the complete shut off of the flow of water through the drainage pipe, the sink or bowl being unfit for further use.

While we have shown and described the preferred embodiment of our invention it will be understood that the same is susipe. h the end of the tubular shank 9 and ceptible of numerous minor changes in the form, proportion, and details of construction, without de arting from the essential features or sacri cing any of the advantages thereof.

Having thus described the invention, what is claimed is: 1'. A device of the class described comprising a flexible hose adapted for attachment to a spigot or faucet a suction head removably secured to the free end of said hose, said head consisting) of a tubular body portion, the end of said ody portion being transversely and laterally fla ed, a flexible suction member seated on sai flanges and extending beyond the circumscribing edge thereof, a securing plate disposed upon said member, and a plurality of bolts extendin through the transverse flange of said head and through said'plate having nuts threaded on their outer ends to secure the suction member in position.

2. A device of the character described A comprising a flexible tube having removable connection to a spigot or faucet, a suction head removably secured on the free end of said tube, the outer end of said head being formed with a transverse circumscribing flan an outwardly inclined flange exten 1n laterally from the transverse flange a flexi le suction member seated on sai flanges, an annular plate dis osed upon said member, and a plurality of olts extending through said transverse flange and plate having nuts threaded on their outer ends to secure the suction member in position.

3. A device of the character described comprising a flexible tube adapted for detachable connection to a water spfigot or faucet, a tubular shank disposed in t e outer end of said tube having a peripheral flange adjacent to its outer'end the extremit 'of said shank being exteriorly threade a suction head having a cylindrical tubular body portion, one end thereof being closed to re-.

rovided with a central open P flreaded upon said shank, the bod portion of said head having a transverse y extending cirand cumscribin flange on its outer end, an out wardly inc ined annular flange formed on the edge of said .transverse flange, a flexible suction member disposed upon the inner faces of said flanges, an annular plate disposed upon said member, and a plurality of olts disposed through the transverse flan e,

the suction member and said plate, said bo ts having nuts threaded on their outer ends to secure the suction member in position.

In testimony whereof we hereunto aflix our signatures in the presence of two witnesses.
